Comparing reconstruction algorithms for different size of object in electrical tomography

Electrical tomography is widely used in industrial process and clinical science because of its characteristics of fast response and continuous monitoring. Image reconstruction algorithms are proposed and developed to improve the quality of reconstructed image. In the continuous monitoring, the size of object is always changing, so it is important to compare imaging ability of different algorithms for different size of object. In this paper, circle models and square models of different size object are established. Through the analysis of image error and correlation coefficient, ten image reconstruction algorithms are evaluated detailed.
